Mix flour and sugar in a bowl, add egg and half of the milk. With a wire whisk or mixer mix for until you have a smooth dough. Then slowly add more milk until the dough is easily running from a spoon - you will need a rather liquid dough to make thin pancakes.

Heat a bit of oil in a skillet, add enough dough to make pancakes about 2 - 3 mm high (you'll need to experiment about how much dough you need, it depends on the size of your skillet). Lightly brown pancake on both sides, put on a plate.

While the next pancake is baking, thinly spread some jam on the finished one. Repeat until there is no more dough left. Don't spread jam on the top pancake, but dust it with powdered sugar and decorate with gummy candy.
